Description
Technical field
This utility model relates to a kind of trace particle delivery device for flume test, particularly belongs to a kind of in tank current flowing test process, carries out single-point, multiple spot or whole flow field and throw in the device of solid, liquid state trace particle。
Background technology
Flume test is one of important method of research flow characteristics and rule。In flume test, what current produced in flow process is difficult to the physical phenomenon of with the naked eye directly observation, it can be shown with form intuitively by the method for interpolation tracer。Conventional tracer can be divided into solid-state (aluminium powder, polystyrene sphere, lucite powder, Pulvis Talci etc.), liquid (ink, milk, dyeing liquor etc.) and gaseous state (electrolysis produces bubble hydrogen etc.) three kinds by the states of matter of particle。
The trace particle measured for wind-tunnel FLOW VISUALIZATION and PIV occurs, delivery device research is more, but its structure is complicated, involves great expense, thus fails comparatively to be generally applicable in flume test。At present, take the input of solid-state trace particle manually uniformly to dispense, discharge the modes such as suspension and carry out, have the disadvantage that it cannot be guaranteed that uniformity and seriality, and the floating of particle or sink substantially, make it that response of current flowing is relatively slow, consequently, it is possible to test measurement result is produced impact；The single-point of liquid trace particle, multiple spot are thrown in and adopted little syringe or aperture release, and when discharging, defect that may be present is: jet causes chromonemal pulsation, or has the velocity component being perpendicular to model surface, and current cause certain interference。The input requirement of trace particle in corresponding flume test, it is necessary to a kind of special, delivery device easily。
Utility model content
Utility model purpose: for above-mentioned Problems existing, this utility model technical issues that need to address are in that to provide the delivery device of a kind of solid, liquid state trace particle suitable in flume test requirement, easy to use, meet requirement。
Technical scheme: in order to solve above-mentioned Problems existing, the technical scheme that this utility model adopts is: a kind of trace particle delivery device for flume test, discharges case including the liquid trace particle being positioned over above tank and solid-state trace particle discharges case, high-pressure air source, connection high-pressure air source and discharges the first high-pressure gas pipeline of case with liquid trace particle, is connected high-pressure air source and solid-state trace particle and discharges the second high-pressure gas pipeline of case。
The beneficial effects of the utility model are in that:
Discharge case release liquid trace particle by liquid trace particle, it is possible to select to control to discharge flow by air inlet and telescoping catheter, or select to inject that gases at high pressure increase spike liquid discharges flow further。And, case release solid trace particle can be discharged by solid trace particle, and utilize the airflow of high-pressure gas pipe way outlet to be broken up by pressed powder, particle granules is very little, can be dispersed evenly in gases at high pressure, entered after air disperses further by unidirectional venthole, ingoing stream flow field, consistent ground。
This utility model is simple to operate, is applicable in flume test the fixed point of liquid trace particle, multiple spot, multi-level throws in and the whole flow field of solid-state trace particle is thrown in, discharges and be effectively ensured uniformity and the seriality that trace particle is thrown in process；And when discharging liquid trace particle, the injection flow velocity of adjustable traced fluid and water velocity are of substantially equal, it is to avoid due to the chromonemal pulsation that jet instability causes；Spike liquid injects along current flow direction, is absent from being perpendicular to the velocity component of model surface, effectively prevent the interference to current。And available device simultaneously, multi-level, multiple spot arranges flexibly and discharges a little；And when discharging solid-state trace particle, comparatively uniformly and particle rapidity less, float or sink inconspicuous, the flowing of current can be responded quickly, and flowing itself not affected greatly。
